Kling AI 2.5 Turbo：悬崖摩托车俯冲

Dawn settles over a high cliff ridge above a sheer ocean drop. From directly overhead, a lone rider pauses at the crest as wind hisses and the engine gathers; he surges forward and lifts clear, the camera tilting and dropping with him until open space reveals a coastal hairpin etched below. Touchdown, suspension compresses, tires bite, then we're at wheel height, locked to the rubber as the road tunnels through rock and slides beneath a glassy surface. He passes through a shimmering membrane and continues along a submerged cliffside path under a wavering blue ceiling; reef drifts by, caustic light dances across fairing and sidewall, bubbles slip from the tread, the world turned low and bassy. The lens arcs to a three-quarter track through twin underwater hairpins, moves ahead, returns for an S-bend, then rises with the route, clean seam back to air, water lifts as mist, tires tick dry, a low rear-wheel pass, and a precise throttle blip into black.
